For thermoplastic polymers, chemical degradation in service has been the subject of much research and investigation. When designing pipes or seals for use in oil and gas applications, this knowledge is essential in estimating the useful lifetime of the component.

Throughout the plastics industry, PEEK is widely viewed as a leading high-performance polymer (HPP). However, the materials of choice in the automotive, aerospace, oil & gas and medical device industries have long been metals. PEEK polymer is fast changing that mind-set.

The widespread use of polymers has revolutionised our lives in the last 75 years or so. There is a wide range from every-day commodity plastics up to high-performance polymers (HPP), such as VICTREX™ PEEK, that are able to perform in very demanding durable applications.

Metals have long been the material of choice in the commercial aerospace market. However, polymer composites are making significant inroads, replacing metals along the entire aerospace supply chain – as best witnessed by the Boeing 787 and Airbus A350 developments.

When designing a critical component for the Energy Industry, material selection is crucial. You need to understand how it will perform in real world conditions, and minimum testing requirements don’t always give you the full picture.
